The 7 Stages of Unit Testing
summary
Walks through a concrete Android Kotlin demo: a SuperVillain data class with a computed fullName getter, a setter that splits names, and an attack(megaWeapon) method. Writes three unit tests that pass: assert fullName equals "Lex Luthor", setting fullName updates firstName and lastName, and verify(megaWeapon).fire() using a mock. Uses Android Studio, JUnit4 and Mockito, discusses coverage measurement, DI, modularization and CI tradeoffs.
